VAPORIZER FOR INTEBNAL-COMBU'STIDN ENGINES.

Application filed February 1, 1924. Serial No. 690,012.

T 0 all whom it may concern:

Be it known that I, LEQNl-IARD BECKER, a citizen of the German Republic, and resident of \Viesbaden, Germany, have invented certain new and useful Improvements in Vaporizers for Internal Combustion Engines, of which the following is a specification.

This invention relates to improvements in atomizing or vaporizing the fuel in internal combustion engines; and it comprises a device for simply and thoroughly atomizing or vaporizing the fuel, whereby a complete con'ibustion of the gases is ensured. Essentially the invention consists in utilizing the principle of the reaction wheel, as for instance, used in water Sprayers in the irrigation of gardens. In carrying out this principle a wheel or rotatable body is set in rotation by the reaction of the working medium issuing in fine jets, whereby owing to the rotation and the spraying tubes the working medium is atomized to the highest extent possible.

The, accompanying drawing illustrates by way of example a suitable apparatus embodying the invention. In the drawing z- Figure 1 is a cross-section through the improved vaporizing apparatus, and

Figure 2 is a plan of the reaction or nozzle wheel.

The same letters of reference indicate similar parts in both figures.

The improved vaporizer is located between the carbureter and the motor, and is preterably attached to the former in some suit.- able wayfor instance, by means of the lower flange on its case 717, so that the gaseous mixture will pass from the carbureter into the vaporizer through the central opening in said flan e, said opening having mounted in it a bearing piece or spider 7. On entering the vaporizer, the gaseous mixture will pass directly into the inteior of a rotating body or wheel Z), provided at its upper part with a peripheral series of bent spraying tubes a, and will produce a reaction which sets the wheel body Z) in rotation in the opposite direction to the direction in which the tube openings point; said body being fixed to.

a vertical shaft g vhich is mounted at one end in the bearing in spider f, and at its other end in a similar bearing piece or spider of drops prevents. complete combustion,

particularly when heavy oils are employed,

and thus constitutes the cause of the disagreeable smoke development. By means of the nozzle 0' located in the lower part of the casing, cold air if needed may be added to the mixture Heating of the working medium is not necessary as extensive experiments have proved that theprocess brings about a perfect mixture and extremely fine atomization. From this it follows that when. a cold gas IIIIXtHIB lS employed the best imaginable volumetric efiiciency of the exploding HIlXtUIBlS obtained. For the pu r-- pose of thoroughly stirring the gas-air mixture prior to its entrance into the reaction wheel, an auxiliary impeller or fan (i is pro vided and is secured to the shaft 9 within the wheel body. I

It will be readily understood that changes may be made within the scope of the invention as recited .in theappended claim.

What I claimras my invention and desire to secure by Letters Patent is A vaporizer for internal combustion engines, comprising a case having an inlet for communication with the carbureter of the engine to. receive the gaseous mixture therefrom, and also having an outlet opening for communication with the engine intake to deliver. the vaporized mixture thereto; a ver tical shaft in said case supported in at least one of said openings; a hollow body carried by said shaft and having an open inlet end which isrdisposed immediately opposite and adjacent to the inlet opening in the case, to permit the gaseous mixture entering said case to pass directly into said bodyfand a series of bent spraying tubesattached to the periphery of sa1d body and through which the mixture 15 adapted to flow, whereby sa d 2f t t I 1,532.866'
